HierarchyPrintOptions Class
Specifies hierarchy print settings.
Namespace: DevExpress.XtraReports.UI
Assembly: DevExpress.XtraReports.v24.1.dll
NuGet Package: DevExpress.Reporting.Core
Declaration
Remarks
Set the HierarchyPrintOptions class properties to print the Detail band‘s data in tree mode.
Specify the properties that define one of two supported data structure types:
Recursive data
Set the ChildListFieldName property to the name of the collection field that your data exposes.Data with ID-ParentID related fields
Set the KeyFieldName and ParentFieldName properties to the names of the ID and ParentID fields that your data exposes.
Use the Indent property to specify the child level node offset in report units.
You may encounter two cases when hierarchically printed data does not fit within a page:
- The child rows do not fit the page’s width
Anchor the data-bound controls to the right edge of the Detail band (their container). For this, set the controls’ AnchorHorizontal property to Right or Both.
Left/None Anchor | Right and Both Anchor |
---|---|
- The child rows do not fit the page’s height
Set the KeepTogetherWithFirstChild property to true to make sure that a parent node is not separated from its first child by a page break.
KeepTogetherWithFirstChild = true | KeepTogetherWithFirstChild = false |
---|---|
Hierarchical print mode supports expand/collapse modes. For this, specify the Detail band’s DrillDownControl property. You can assign any control that is located in the Detail band to this property. For instance, you can add the XRCheckBox control to the Detail band and use it as a drill-down control.
You can use the CurrentRowHierarchyLevel variable in expressions to get the current hierarchy level’s index. For example, you can use this variable to highlight hierarchy levels.
Sort fields are supported in hierarchical print mode. You can sort data on each hierarchy level.
Note
You cannot use HierarchyPrintOptions if you use MultiColumn options.
